Boerhaave is a full-thickness tear, usually left posterolateral in the distal esophagus, after a vomit against a closed glottis. Mackler triad (vomiting, chest pain, cervical crepitus) is useful when present and often missing. Do not wait for neck crackle. CT with water-soluble oral contrast is the first test. Drain what has leaked. Cover or repair the hole. Endoscopy is a therapy tool after CT, not a screening EGD.

Clinical Pearls

  1. Vomiting then sudden chest or back pain is Boerhaave until CT says it is not. Crepitus is late.
  2. Mallory-Weiss is a mucosal tear at the GEJ that bleeds. Boerhaave soils the mediastinum. They are not grades of the same injury.
  3. Do not start with a diagnostic EGD. CT chest and abdomen with oral contrast first. Low-insufflation endoscopy is for selected endoscopic therapy.
  4. A covered stent without drainage of the pleural or mediastinal collection is not a plan.
  5. Small iatrogenic tears recognized during an endoscopy are a different conversation. Mechanical closure: TTS clips.

Boerhaave: Mackler Triad Is Incomplete, CT First, Then Drain and Cover or Operate

Transmural distal-left rupture after vomiting is a mediastinal emergency. A mucosal Mallory-Weiss tear bleeds. It does not soil the chest.

Clinical Bottom Line

Question Practical answer
What is Boerhaave? Spontaneous transmural rupture, usually distal left posterolateral esophagus, after vomiting. Mediastinitis and pleural contamination, not hematemesis as the main story.
Mackler triad Vomiting, lower chest pain, subcutaneous emphysema. Incomplete in many series. Do not require all three.
First test CT chest and abdomen with water-soluble oral contrast. Swallow study if CT is equivocal and suspicion stays high.
Endoscopy Not the screening test. Use it, with low insufflation, when you already plan endoscopic coverage or to define a tear the CT already found.
Treatment NPO, IV antibiotics covering oral flora, acid suppression, drain collections. Covered SEMS or vacuum therapy for selected contained leaks. Surgery if uncontained, delayed, or unstable (WSES 2019, PMID 31164915).

How is this not Mallory-Weiss?

Mallory-Weiss is a mucosal laceration, usually at the GEJ, that presents with bleeding after retching. Boerhaave is a blowout through muscle. The patient looks septic or has a hydropneumothorax, not a stable GI bleed. There is no Mallory-Weiss permalink in this set. Keep the distinction on this page instead of inventing a second URL.

The weak point is the left posterolateral distal third, a few centimeters above the GEJ, where surrounding support is thin. That is why left pleural fluid and mediastinal air are the CT pattern you look for.

What does WSES actually want?

Chirica 2019 (PMID 31164915) is the World Society of Emergency Surgery esophageal-emergencies guideline. Time to source control is the variable that moves mortality. NPO, resuscitation, broad antibiotics, and drainage of pleural or mediastinal collections are not optional add-ons to a stent.

Iatrogenic perforations recognized during the index endoscopy can often be closed immediately with clips or a covered stent. Spontaneous Boerhaave is not that case. Endoscopic coverage is reasonable for selected contained leaks when a multidisciplinary team can drain the chest. Uncontained soilage, delayed presentation, and hemodynamic instability still belong to surgery.

Covered stents, when used, stay long enough to seal, commonly in the 2-4 week range in the WSES discussion, then come out. Endoscopic vacuum therapy is an option in centers that already run it. Neither device replaces a drain.
